fix: make Valkey service headless for StatefulSet DNS

Browse source 
Sentinel requires individual pod DNS names to work correctly.
Making the valkey service headless enables DNS resolution for:
- valkey-0.valkey.towerops.svc.cluster.local
- valkey-1.valkey.towerops.svc.cluster.local
- valkey-2.valkey.towerops.svc.cluster.local

This fixes CrashLoopBackOff in valkey-sentinel pods.
